Digitization of TV – An Opportunity to Build an Open Access Future Proof Next Generation
TV Network Infrastructure in India
Background
While the digitization of TV is going on in the country and in the digitized TV
era, we are going to live forever for TV services, it is important that we have
a future proof ecosystem in place. IP in the core, edge and access is there to stay.
Copper and coaxial might give way to OFC to give coverage up to the premise, building
or curb. As a policy, we need to allow a consumer to choose the Digital Addressable
System (DAS) Headend Service Provider (HSP) of his/her own choice. We already provide
freedom to a mobile subscriber to change the service provider through the MNP. For
TV, Set Top Box (STB) is akin to a mobile hand set and monthly billing for a TV
connection might be more than a low end pre-paid mobile connection. Just like a
mobile subscriber is free to select the Mobile Network Operator (MNO), a digital
TV consumer is also allowed to select the DAS HSP out of the available ones in the
dependent geographic service area.
Open Access Digital TV Infrastructure
As this is not mandatory today, thus DAS HSPs are mostly deploying Digital Video
Broadcast (DVB) technology both for head end and distribution. For transport of
DVB signals from headend to LCO interconnection node, DAS HSPs use optical nodes
over fiber. This is rigid and makes a digital TV consumer dependent upon the service
of one DAS HSP only. The rest of the world namely US, EU and other countries when
they digitized TV, DVB was the only cost effective technology.
India is one of the late entrants in this. This also has an advantage as we can
truly deploy a world class future proof NGTVN infrastructure and not follow what
rest of the developed world has done. We are known for not very good conceptualization,
planning and execution of national level infrastructure projects. Our roads and
flyovers before commissioning start getting choked. We need to promote those technologies
which allow open access and are future proof. The technologies for digitization
of TV are DVB, DTH, IP TV and DTTB. DVB has already proven itself to be the best
in head ends and CPEs and IP and/or MPLS have proven to be as universally acceptable
underlying technologies for Next Generation Network (NGN). Here is an opportunity
to induct DVB and DVB over IP/MPLS selectively to realize a true NGTVN.
Open access IP based technology is highly ubiquitous and affordable. This is an
opportunity for us to be future proof. DVB over IP offers best of both the worlds.
It uses the proven MPEG Transport Stream (TS) at the head end, and for transmission
and distribution, it uses the ubiquitous IP. At the consumer end, it again uses
the DVB STB. Such a technology allows even the digital TV consumer to select the
DAS HSP. We have more than 60,000 Local Cable Operators (LCOs) and 5000 Multi Service
Operators (MSOs). None of them goes out of business and the country gets a state-of-the-art
DVB over IP digital TV infrastructure conveniently riding over the Next Generation
TV Network (NGTVN). Very minimal incremental cost needs to be incurred by both DAS
HSPs and LCOs. For country deploying a future proof digital TV infrastructure so
late, even if we have to allow more FDI in this industry, it is worth.
Consumers - Pick and Choose Your Own Digital TV Service Provider
India is now on a national mission for an infrastructure which must be state-of-the-art,
scalable, future proof, affordable and above all meet the requirements of all stake
holders, i.e., content providers, infrastructure providers, consumers and government.
The consumer does not want to be tied down to a particular service provider whether
wireless or wire line. A consumer spending 50 L on a flat cannot be told that for
your wired telecom needs you have only X service provider, for your wired TV service,
you have only Y digital TV provider and only Z as IP TV provider. The government
must come out with regulations and policy which only allow open access wire line
infrastructure which is already adopted in case of wireless. An open access wire
line infrastructure must not be implemented by multiple access operators bringing
their own wires into the premise. Instead, it should be done through seamless interconnection
at the node where main infrastructure service providers and open access infrastructure
service provider actually interconnect. With such infrastructure chain, the consumer
has an option to pick the main service provider who is fully equipped with OSS/BSS/CRM/SMS/Pre-paid
and gives a better QoS and customer experience. The open access operator like LCO
partners the main service provider like DAS HSP. Each open access LCO has main DAS
HSPs in the geographic area of the consumer interconnecting with each other at the
node and through a simple process, a consumer, if unsatisfied, can change his DAS
HSP, and may be within two weeks as against one week for MNP. In case, there are
any incremental financial overheads, let these be split between the consumer and
the new DAS HSP because open access LCO is really a pass through and he can be compensated
suitably for his coordination role by the new DAS HSP as he gets a new customer.
To achieve the above, the government must do three things, make open access mandatory
over a reasonable period of time, enhance FDI and allow RoW to this industry.
Opportunity for DAS HSPs to Share OSS/BSS/CRM/Pre-paid Infrastructure with Telcos.
Creation of NGTVN is a great step. Being ubiquitous, there is a scope for DAS HSPs
to share the telcos OSS/BSS/CRM/Pre-paid infrastructure rather than setting up their
own. Both telcos and DAS HSPs would get benefitted. Incremental capacity creation
of infrastructure costs less and enables better utilization. While both compete
in the market place but they share the infrastructure.
Interoperability of STBs
Interoperability of STBs needs to be made mandatory. Both DTH and IP TV have not
been able to achieve this due to very lax regulations and possibly costlier technology.
Both technological and commercial issues need to be resolved and suitable policy
needs to be in place. Subscribers cannot be expected to pay for new STB should they
decide to change their DAS HSP. At best, they can pay for overheads involved in
the changeover process.
Unlimited Value of Open Access Infrastructure to GDP Growth
Let us look at the wider pay offs of the above for the country's GDP. If the above
is implemented, IP truly becomes ubiquitous to 150 million HHs, a stepping stone
for world's largest, quickest and cheapest NGN in India. This NGN powers up the
rapid proliferation of much needed BWA for which the country is struggling. As against
100 million broadband target, only 13.7 M subs that too majority with 256 kbps,
the world's lowest speed qualifying for broadband subscriber has been achieved,
making us a laughing stock on all global broadband forums. Government is contemplating
NOFN which leaves access up to the operators. We have seen since 1994, how much
high speed state-of-the-art access capacity has been created by the national operators.
They would build access with 3G, 4G, 5G etc., thus country is left high and dry
as virtual education, healthcare services etc. cannot be delivered satisfactorily
to very large number of subscribers say for sustained classes to 87 % college dropout
students who want to work from 9 am to 5 pm and study graduate and PG courses from
8 pm to 11 pm when they are back at home. Likewise, multispecialty hospital based
diagnosis, consultation and prescription services to 70 % HHs can never be provided
on wireless alone.
Back haul for Wireless. If India gets truly a NGTVN then IP connectivity
would be available at every digital TV House Hold (HH). Minimum 100 million HHs
by 2014 get covered by ubiquitous IP infrastructure. Nation has embarked upon creating
a National Optical Fiber Network (NOFN) through Bharat Broadband. NOFN does not
address the access whereas DVB over IP is an end-to-end infrastructure conveniently
riding over NGTVN built around NOFN in the core and edge and providing the much
needed state-of-the-art access and the last mile. Moreover, Broadband Wireless Access
(BWA) providers would be deploying LTE and femto cells. This IP infrastructure would
be ready to provide them the much needed back haul oxygen for which telcos are struggling.
This is an opportunity for DAS HSPs and LCOs to offer the backhaul connectivity
and treat it as an additional revenue opportunity.
Wi-Fi Hot Spots. DAS HSPs along with LCOs can offer a huge number
of Wi-Fi hot spots in the country again enabling early penetration of true broadband.
NGTVN Catalyzes GDP Growth Enhancement. Telcos, MSOs, LCOs, DTH
operators etc., are all infrastructure providers with voice, data and video as bearer
services. While voice is primal in nature, data and video services enable innovators
to do unlimited things beyond imagination. Broadcast TV is a specialized form of
video service. Digitization of TV exercise (which is already being done through
the DTH TV and IP TV services and now getting expanded rapidly by the Over The Top
(OTT) players) by the government over cable is an attempt to bring to 150 million
HHs (assuming rest of 75 M HHs are shared between DTH and IP TV providers) an affordable
QoS with ability to select the programs of one's choice. This is highly an infrastructure
exercise, the fruits of which will be enjoyed by the DAS HSPs, LCOs, content providers,
consumers, government and nation. This has a potential to catalyze GDP growth driving
services like virtual education, virtual healthcare, virtual transportation, e-agriculture,
much needed e-governance etc. so heavily dependent upon both true and mobile broadband
and would get commercially launched only to boost up the GDP by minimum 2 to 3 %.
The country must not miss this opportunity now. TRAI, MIB, MICT (DoT and DIT) must
consider these inputs and give the country a future proof NGTVN and consumers the
much needed choice to select the digital TV service provider.
